摘要
石油热转化过程包含由物理化学因素引起的相态分离与转化。第二液相的出现是相变化的初级阶段,碳质中间相的形成是相变化的中间阶段,焦的形成是相变化的高级阶段。与沥青质和碳质中间相类似,第二液相也是一种溶液度类物态,其工作定义为甲苯(或苯)不溶而为喹啉(或吡啶)可溶物。
In the petroleum thermal conversion, there exist phase separations and transformations resulted from the physical changes and chemical reactions of the feedstocks. The occurence of the second liquid phase, the formation of the carbonaceous mesophase and the coke deposition are respectively the initial, intermediate and final stages of the involved phase transitions in the thermal conversion system. Like the asphaltene and the carbonaceous mesophase, the second liquid phase is treated as a solubility class with the toluene (or benzene) insolubles and the quinoline (or pyridine) solubles as its tentative working definition.
